65 TR6 I put together the best gearbox that I could from the bins of parts the owner gave me. I now suspect that at some point the factory changed thread count on the clutch end (and possibly the opposite end) of the mainshaft. Can anyone confirm? Thanks, Mike
Hey Pete, were you at Broadford on the weekend? I broke the 5 speed and the box in practice on Sat and spent all day making a new one. Late Sat I discovered 5 speed mainshafts have a different thread next to the taper, you know the one that holds the clutch on. The one that you dont know is different until you need to replace it at a race meeting and the blokes you race with are out there doing laps.
Sunday-dont go there.
